"1 o cit whom it may concern: 4

Be it known that 1, JOHN W. SWINDELL, a citizen of the United States, residing at Greenville, in the county of Hunt and State of Texas, have invented a new and useful Vibrator, ofwhich the following is a specification.

This invention has reference to improvements in vibrators for the production of rapid vibrations for the treatment of disease in a manner similar to massage treatment.

The object of the present invention is to produce an instrument whereb a person may treat himself or herself, being enabled by the construction of the device to set the to reach any desired part of the same so as .bod

T e invention consists essentially in a case or body containing a train of gear with an element for producing movements oi the whole structure with a crank or handle so arranged that it may bev applied to the gear thereto from the outside of the case at the volition of the operator. Attached to one end or the case is a contact head ca adjusted to an arc of considera le range and at the other end of the case there is attached a handle also adjustable through an arc of considerable radius, so that an operator may so adjust the handle and contact head that a person i may mechanism, part of his or her person with the'contact vibrations.

give self treatment by best understood by a The invention will be consideration of the following detailedde,

takenin conneotion'with the acsoription, companying drawings forming part ofr the specification,-inwhich, Figure 1 is a'face view of thedeviice with parts removed and other parts shown in sec- I tion, and 2' is a side elevation with-the es shown in section.

near roun ed ends and with the face 2 and rear wall 3 parallel one with the other and spaced to a less distance apartthan the side or end walls.- Extending longitudinally through the casing and attachedto the front walls are two straps 4 parallel one with the other and extending beyond'the endsiof the otfcasing, asshown at5 andfi,

. Extending through the straps 4 .and

rapid vibratory train to impart motion able of being not only drive the vibrator? but may also reachalrnost any sad, so that by the device one is enabled toone llldlerring m dic-drawings, there is shown I a 1 of general-"rectangular shape withand rear through the walls of the e g near one end thereof is an arbor 7 having its ends beyond the casing s uared, as shown at 8, so as to receive the sogket end 9 of a crank 19. The a! bor 7 carries a gear wheel II'meshing with a pinion 12 on another arbor l3 journaled in. the straps-4, and this arbor 13 carries a gear Wheel 14 meshing with a pinion 15 upon an arbor 16 journaled in the straps 4 elqsotoone 65. end of the casing 1. Arranged eceentricall upon the arbor 16 is a weight 17.

When the crank '10 is manipulated; rota. ry motion is imparted to the gear wheel it, thus driving the arbor 13 at a' much higher to speed, and the gear wheel '14 on the erhorltd irn arts to the arbor 16 a proportionately hig er speed. ,Now, the Weight 17 being in an unbalanppd condition, tends to impart e and the vigor of these movements W'llll depend upon the speed at which the arbor 16'is' driven. By means of the gear train the speed of the arbor 16 may be'quite high,.and

" very rapid shocks or vibrations otconsiderv as able amplitude are imparted to the stamped and easing 1, and any arts carried thereby.-

- Extending through t e ears 5 is a bolt-18 I receiving at its threaded end a thumbinut 1'91, and between the ears inder'20 in which is tapped a radial. nut or the reception of the threaded end ot the stem" 21 on the other end of which there is secured a contact pin 22 of suitable she, e and sine for application loosening'the thumb nut 19, the'cylinder 20' may be adjusted about the am's' ofthebolt 18, sothat the head 22 may beset-at various angles through an arc of 180, or more.

The extensions 6 of thefstraps e have so passed through-theme bolt 23 the threaded end of'which receives a thumb nut 24:, and upon this-bolt there is carried a cylinder 25;.

' havin tapped in it a radial nut for the'recep tion 0 the stem 26 of a handle 27. By loosening the nut 24,- th'e handle may be adjusted. I through anarc otslipproximately 180 to be clamped ii the ajusted position by the thumb nut 24. f

By a suitable adjustment-of the head 22 105 and handle 27, it is possible to reach rtions of the body usually inaccessible to t i-individual when. attempting self treatment, while at the same time, the user is enabled to operate the crank to .put .thegeartrain and vi- .brator unit into-operation? a The improved instrument is entirelyindi violent movements or shocks to the structure, 115.

' What is claimed is a tram of gearing therein, a vibrator element also housed in the casing and driven by said ,/tra1n .of gearing, means for imparting motion to said train of gearing, a vibrator head adjustable with relation to'its angle of rojection from the su port, and a, handle a s0 adjustable with rel tion to its angle of projection from the support.

2.. A vibrator comprising a suitable casing, a train of gears within the casing, an eccentrically supported Weight driven by said gears and also housed in the casing and constituting a vibrator element, a contact head exterior to the casing and adjustable with relation to its angle of rojection from said support, and a handle a so adjustable with rela- A vibrator comprising a suitable casing,

tion to its angle of port.

3. A vibrator comprising a suitable casing projection from the suphaving parallel front and rear walls, straps on ment comprising an eccentrically mounted weight housed within the casing on that ele- 5 ment of the gearing remote from the drive arbor, rotatable blocks or cylinders mounted between the projecting ends of the straps, screw clamps for the blocks or cylinders, a contact head carried by one cylinder, and a handle carried by the other cylinder.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
